I would also add it doesn't pick up shots out of the black very well if at all. I stopped shooting in the white a while ago but might be worth considering if 'you' (anyone reading this) don't tent to keep all your shots in the black. If it knows you shot 5 but can only see 3 it will drop 2 in which you can manually move.
